T zZZwLom t may conce/rn.'

Be it known that l, EUGENE L. GREENE- wALD, a citizen of the United States, residing at Washington, District of Columbia, have invented certain new and useful llin- Applying Closures, of which the following is a speciication.

My invention relates to a method and apparatus for closing the ends of tubular bodies and has particular reference to a inachine for securing a head or cap to the end y of a can or similar article.

The primary object of the invention is to provide a machine for automaticallyseaia ing the heads or covers on can-bodies or similar articles by corrugating mechanism so that the seal will be perfect and-so that the can will be readily openable without rupturing any of the parts of the can.

further object is to provide novel means for feeding` the can-bodies to the machine and novel means for feeding the caps to the bodies. Y

A further object is to provide a stationary seaming table andv novel mechanism for moving the cans to their successive positions on said table. t

Another object of the invention resides in the mechanism for placing the caps on thev forming a bead or shoulder on said members. The said mechanism may be designed so that only the cover part is corrugated and bent into locking position, or so that a bead n is formed on said kbody only.

The above and other objects and the novel features of the invention will be apparent from the following description taken in connection with the accompanyingdrawings in which Figure 1 is a horizontal sectional view of `a machine embodying my invention, the secV- Specification of Letters Eatent.

Referring to the drawings, 25 designates a stationary platform which supports the parts of the machine. The platform25 is substantially circular; andv is supported above the floor by the legs 26. The platform 25 has a laterally projecting part 27 at'one side which supports the end of the Vcan feeding mechanisin and the devices which automatically control the delivery of the cans to the canv supporting table 28. The table 28 is stationary and has a flange 281 to receive the bolts 282 by means of which it is rigidly secured to the central supporting standard and bearing 29. The member 29 has a'base flange 291 and is mounted on the platform 25 at the center thereof and secured to saidplatform by bolts 292, which bolts extend through the flange 291, platform 25 and flange 301 of a bearing 30, holding the latter in place against the under side of the platform.` i

The mechanism for moving the cans C or similar articles along the surface of thetable 28 comprises a series of pusher arms 31, eight in the present instance, which are arranged radially of the table 28 and secured at their inner ends b bolts 311 to the top side of a wheel 32 which has the radial slots 321 and concave recesses 322 which form part of a Geneva gear mechanism whereby a Step by step or intermittent rotation is imparted to the wheel 32 and arms 31 mounted thereon. At the center of the machine, the arms 31 and wheel 32 are provided with oppositely extending flanges 313 and .323 which bear against the table 28 and flange 291 and form a hub therefor whereby the arms and wheel are rotatably mounted on the standard 29.

The driving member of ther Geneva gear mechanism comprises a roll 33 rotatably mounted on the end of an arm 331 integral with the disk 332 `which is mounted A.on-the main vertical drive shaft 34 to rotate therewith. The disk 332 has apart of a peripheral curvature to fit the concave parts 322 of the wheel 32 and has a recessed portion 333 so that it will clear the ends ofthe portions having the radial slots 321. Each revolution of the shaft 34 and disk 332 serves to rotate the wheel 32 and the arms 31 aneiohth of a revolution and during each revolution of the disk 332, the wheel 32 and arms 31 will have a period of movement and a period of rest as is common in this type of mechanism;

Referring to Figs. 9 and 12 it will be seen I that the shaft 34is mounted in the bearings `341 and 342 and is continuously `rotatedby an electric motor which is connected to the shaft 34 by the gears 343 and `344. A sprocket wheel 35 is mounted on the shaft 34 and is connectedV by a chain 351-to a sprocket wheel fixed on the lower end of the spindle 36 which is rotatably mounted in the stationary bearing sleeve supported ony the extension 27 of the platform 25. A stationary cam 38 is supported on th upper end of the sleeve37 andhas a peripheral cam surface upon which the roller 39 runs. The roller 39 is mounted on the inner end of an extensible arm 40 slidably `mounted inthe guides 41, 41 on the under side of the rotatable arm 42 fixed on the spindles 36. When the spindle 36 rotates the arm 42 rotating therewith,` carries the extension40 thereof around and as the roller 39 on the latter is held in Contact with the cam surface 38 by the spring401, the member 40 will moveinward and outward along the arm 42 according to the path defined by the cam 3 8. The lengthof the can-moving arms 31 1s such that they extend beyond and clear the outer edge of the table 28, the outer ends of the armsV having upwardly extending portions 314 projecting a distance above the top of the table 28 and portions 315 which extend radially inwardly above the surface of the table.y The inclined blocks 316 and the resilient concaveV can-engaging members 317 are mounted on the forward sides of the portions 315. The members 317 are normally shaped so they are of a curvature of less diameter than the cans. The arms of the members 317 are opened slightly when the cans are pushed into the curved sockets formed thereby, whereby the cans are firmly grasped so they willnot turn in the pockets and to further prevent turning in the pockets, the inner concave surfaces of thel members 317 are provided with transverseribs 317 or otherwise roughened to produce a frictional holding face which contacts with the cans. The members 317 holdthe cans outwardly against the rim flange 283 and cooperate with said flange 283 on the table 28 to keep the cans moving in a fixed path as the arms 31 are rotated. The inclined blocks 316 are arranged to engage the trip lever .44 which operates to release a can just as a can-engaging member 317 is in a proper position opposite the can-feeding mechanism to receive it.

From. Fig. 1 it will be seen that each revolution of the spindle 36 causes acan to be movedl from the belt conveyer 43, across the bridge 431 and gap 432 onto the table 28 and into the concave canengaging member 317 in position to receive the can. The belt V43 which conveys the cans C from the fillingmachine or other apparatus has guide rails 433, 433 extending along the top at the sides thereof and the beltpasses around a roller 434 which is journaled as close as practicable tov the table 28. The intervening space isbridged by a plate 431 except for a narrow gap 432 through which the` upwardly extending portions v314 of the arms 31 pass.

ion v The trip lever 44 is pivoted intermediate -i its ends on the support 441 and is yieldingly held in the position shown in Fig. 1. The outer end of the lever 44 is connected by a chain or other flexible device 443 to one arm i 451 of a stop dog 45 which arm 451 is connected by a chain 452 to the arm 461 of a second stop dog 46. The dogs and 46 are pivoted intermediate their ends on the sleeve 37 and support 462 respectively and the arms 451 and V461 are held in a` fixed position by` the springs 453 'and 463 respectively, connected to the supports 462 Legans vand 464 respectively. The springs 453 and 463 exert a tension on the chains 443 and 452 respectively, and serve `to yieldingly hold the end 444 of the lever 44 in the path of the tripping blocks 316. .lVhen the lever 44 is tripped, the dogs are rocked on their pivots and the arms 455 and 465 thereof are moved out of the path of the cans which they engage. The continuously moving' belt 43 and feed device 42, 40 then v coperatie to move the can released by the vtion by the spring 468 while both prises a arm 455 onto the table released by the dog 46 be 'engaged immediately the dog 46 is 28, whereas the can moves vforward to by the arm 455, as the latter is restored by the spring 453 and also returned to its initial posisprings by reason of their fiexible connection with the lever 44 restore the latter to a position in the path of the next arm 31. When a can has been moved onto the table step of the conveying arm 31 moves the can to station B where the cans are trued up and where the caps areinitially secured in place.

Referring to F ig. 2t each' cap a comdisk-like member having, if desired, a depressed central portion and a flat peripheral rimvportion c provided at intervals of 120O with integral radial tongues t. The exterior surface of the peripheral wall w of the depressed portion has a continuous groove g therein which contains solder, albumen or some other suitable sealing or securing medium. r1`he rtongues are designed to be doubled on themselves and tucked beneathV the usual outer flange on a can, the ends of the tongues being left projecting frombeneath the flange to provide means whereby the cover may be easily detached from the can.

As will be seen from Figs.y 1 andv 2 the can comes to rest atV station B directly beneath a substantially cylindrical magazine 50 of slightly greater diameter than the can caps and provided with three slots 501 extending longitudlinally thereof to receive the tongues t on the caps, which also serves to guide the caps so that they will discharge from the magazine with the tongues thereof at the proper points to be operatedjon by the tongue folding or tucking mechanism. There are usually as many tongue tucking devices as there are tongues on the cover and in the present instance there are three, but since they are alike only one of them will be described.

rEhe stack of caps is supported in nestedV relation at a point above the bottom of the magazine 50 by the members 51 which operate to slightly separate the bottom cap from the stack. n

Three similar members 51 are provided, each of which is pivoted at 511 in a recess two proj eetions 28 at the feeding station A, the nextl 502 in the wall of the magazine 50 and has a rounded nose 512 at its lower end projecting inside the magazine to engage under the stack of cans to support the same. The nose 512 is normally held in its projecting' position by a spring 513 which allows said nose to be depressed into the recess 502 when a cap is removed from the bottom of the stack. Above its pivot the member 51 has 514 and 515 adapted to project into the magazine when the nose 512 is depressed. The projections 514 hold up the stack of caps till the noses 512 return to their normal position when the projections 514 will release the stack and let it down onto the noses 512. The projections 515 enter between the second and third caps fromV the bottom to separate them, should they become wedged together.

rlhe device for taking the caps off the bottom of the stack and placing and holding them on the mouth of the can comprises two similar plates 52, 52 both of which are pivoted on the pin 53 which is mounted near its opposite ends in the parallel brackets 54, 54. The pair of brackets 54, 54 is rigidly secured to the magazine 50 at opposite sides of each of the slotsy 501 therein and at the lower end thereof. Each pair of plates 52, 52 moves together, and the plates of each pair are spaced apart so that they will allow the tongues of the' caps to pass between them and so that the beak 521 of the plates will engage the peripheral flat portion of the cap on opposite sides of the tongue. r1`he beak 521 of each plate is pivotally mounted at 522 on the forward end of the plate and the rear edge thereof fits in a recess, a spring 523 servingto normally hold the beak 521 in'its extended position, but permitting it to yield when the plate passesthe bottom of the stack on its return upward to normal position of the cap removing devices. Each plate 52 has an outwardly extending arm 525, and the arms 525 of each pair of plates are connected together at their outer ends by a pin 526 whereby the plates 52, 52 of each pair may be rocked in unison on the pivot pin 53. A link 527 is connected at each end of the pin 526 outside the arm 525 and extends upwardly where it is pivotally connected to a bracket 551 extending outwardly from a sleeve 55 slidable along the outer surface of the magazine 50, said sleeve being provided with the enlargement 552 adjacent the slots 501 so Vthat the tongues on the caps may freely kshafts 57 and 58 journaled in the bearings y571 and 581 'respectively on opposite sides of the magazine. The 'sleeve 55 is connected mits power from the sprocket 59114 fixed on the main drive shaft Se to the sprocket 591 xed on the shaft 59, and the sprockets being of the same size the shafts will rotate at the same speed.

The sprocket 595 on the shaft 59 and ben low the sprocket 591 drives a chain 596 which drives a sprocket 611 fixed on the sha'lt 61. rl`he shaft 61 is journaled insuitable bearings 612 on the upright 613 and leg 26 and transmits power to the shaft 58 through the gears 582 and 583. y

When the cover has been removed from the bottom oi'f the stach by the remover devices comprising the plates'52, 52, the latter at all three points around the periphery o' the can assume the position shown in Figs. 2, 6, 7, and 8, and the devices which tucl; or double the tongues beneath `the flanges on the cans begin operating.

The folding and tucking means comprises the members and 63 which are pivotally mounted on the pins 621 and 631,

respectively, which are carried between the plates 52, Vlfhe tuclrers 62 and 63 are held in their initial or normal position as indicated in Figs. 5 and 6, by the torsion springs 622 and 632respectivcly. Those springs 622 and 632 surround the pins 621 and 631 and serve to restore the members 62 and 68 to their normal positions after the tuclzing operation.

rlhe initial position of the devices alter the cover has been removed from the magazine and placed on the can is as indicated in Fig. 6. A downwardly moving pair of rollers 6111, 6&1 carried by a sleeve 61Vengage the tuclrer member 62, the tuclzing linger 623 or which engages `the top surface ol! the block 63. The' members 62 and bend the tongue t at t and bend the end thereoiz down against the top surface oit an anvil 65, see Fig. 7. A iurther downward movement ot the roller bei does not alter the position oit' the block 6B but the niember 62 will be swung still further onl its pivot and the tucning part 626 tliereofwill bend the tongue et the tongue upon itself beneath tliepflange on the can and leaving a part projecting` from beneath the flange for a dctaching grip.

FElie sleeve 641 which imparts the motion to the rollers 6/11 carried thereby is located below the sleeve 55 and also slides along the l surface of the can t at t2 thus doubling a part ously nieve in opposite directions and there-` ifore will not intel-ier rhe shaping molds and anvils 65 and 651 which lit beneath the iiange on the can are each semi-circular in shape to conform when closed to the shape of the outside ot the can, serving to true up the can body and they are each provided with shallow recesses to correspondto the width` oi the members 62 and 63 aiidflocated at the points where the tongues on the cans are posi ioned. The shaping anvils and 651 are horizontally slidable on the brackets or supports 652, 652, fixed t0 rigid parts ot' the machine. The rotary cams 671 and 67 are fixed on ythe shafts 61 and 672, respectively, the latter being geared to the shaft 57. Said cams 67 and 671 have grooves which receive the antifriction devices on the stems 673, 67 3 of the anvils 65, 651 and move the latter horizontally into closed and open position as the cans arrive and depart, the cams' being designed and timed so as to `leave the space between the brackets 652 open when the cans are moving to and from the cap receiving station.

'libe cams 56, 56 and 66, 66 are of course de- 100 signed and timed to operate when a can and the aiivils are in cap-receiving position, and by means of the devices which those cams control the caps' are secured to the anges at three points and are prepared vfor the 105 after which they move onward to the seamy 110 ing station S. y

rEhe can being at rest at the seaming station and having its flange still extending yout normal-.to the body and having its cover temporarily secured thereto, is engaged by115 the semi-cylindrical shaping members 66 and 681 which arecomplementary and provide a mold to shape the can for the operation thereon of the seaming devices.

rlhe mold members 68 and`681move hori- 1,20

zontally into positionto engage the outer body and then along the latter upwardly so thatits upper edge will Abe positioned so as to engage the under side of Ythe can flange when the sea-ming opera- 125 tion begins.

The horizontal movement of the mold members 68 and 681 is eliected simultaneyously by means of two cams 69 and 691 which are mounted to rotatev with the verti- 130 70 which extends horizontally above the.

seaming station, being j ournaled in the frame members 71 and 7 2 and geared to the central shaft 59 by the gears 73 and 74, the' latter being fixed on the upper end of areduced section of the shaft 59.

The means for supportingv and operating` the halves of the mold are similar and therefore the means associated with ,the member 68 only will be described. Referring to Figs. 9, 10 and 11, the mold 68l is provided on its convex side with two flanges 75, 75, which are each engaged on their under sides by a series of lugs 761 which are-formed integral with the curved plate 76. Each curved plate 76 has a rearwardly projecting lug. 7 62 which is provided with a roller `763 that fits a groove 694 in the cam 69. Because of this positive connection the rotation ofthe. cam

69 causes the inward and` outward movement Y of the plate 7 6. Near the upper and lower edges of the convex side of the plate 7 Gthere are attached a series of lazy-tongs devices 77 which. have their inner ends rigidly mounted on the concave inner side of a curved supporting member 78 carried by the table 28. The curved supporting member 78 has an opening extendingtherethrough to allow the free movement of the cam 69, and said supporting. member is braced at the rear by the part 781.

The vertical movement of the mold section 68 is obtained from a cam 79 which is keyed to and slidable along the sleeve. 791,

which latter is rotatable with the shaft 792V geared to the shaft 692 by the gears 793. The shaft 792 is supported horizontally in suitable bearings land has a. groove 794 to retain the rollers at the end of the rod 8O which is supported vertically and works in guide openings in the central lugs 761 on the plate 76. The rod 80 isv welded or rigidly secured to the iange 75.

The cams 69 and 79 are so constructed and timed that the cam 69 first moves the moldsection horizontally toward and against the can body. The cam 79 during this stepv of operation slides along the sleeve 791,

tliecam grooves 7 94` and 824.being so shaped as to produce a dwell for the rods 8O and 823 and hold them against upward movement, the cam 79 turning but imparting no` motion to rods 80 and 823. When the mold sections are up against the can body, the rods 8O and 823 are lifted by the cam 79 into the position, as shown in Fig. 10, this movement taking place in a relatively briefV interval of time to give sufficient time for the seaminfr operation. At the upwardend of the stroke there is a slight dwell in they cam while the seaming devices operate when` the movement of the parts reverses' t0- restore" the parts to their initial position for the suc-I ceeding can.

The upper edge of the mold sections 68 and 681 are each provided with a series of notches 8l in which the lower corrugating hngers 82 are pivoted. Each ofthe corrugating devices 82 has a rod 821 connected to the under side thereof intermediate its ends. The rods 821 have their lower ends pivotally connected to a split ring 821 which is raised and lowered at the proper times by a rod 823. The rod 823 is guided vertically by a hole in the lower of the flanges 75 and has its lower end retained by a cam groove 824 in .the cam7 9, whereby it is reciprocated.

Then the mold raised position, the gage the under side of the flange on the can, as shown in Fig. 13, the finger 82 shown inV that figure being somewhat longer than other fingers and being designed tofit the tab which has been flange` on the can, as previously described.

At the same time that the-fingers 82 are in" engagement with the under sideof the iiangei on the can, theperipheral edge portion of tucked under the;

sections 68, 681 are in f radial fingers 82 enthe upper side of the cover is engaged by the upper radial corrugating lingers 83, at-

on the fiange 832 having the top' 833 which is rigidly secured or weldedy to a head 84 slidable in a central opening in the circular member 85. Motion is imparted to the head 84 by a rod 841 connected to a cam 842 mounted to rotate with the shaft 70.

The member 85 is connected by the rods' 851, 851 to the cams 852, 852, which are Xedto rotate with the shaft 70 and reciprocate the member 85 up and down in the annular bearing 86 which is connected at its opposite sides to the frame members 'f1 and 72 by means of the brackets 861, 861. An annular plate 87 is connected to the lower Vside of the member 85 and has an inwardly extending flange 871 spaced from the bottom face of the member 85, whereby a circular recess 872 is formed to receive the outer ends of the fingers 83 which carry antifriction rollers and move radially into and out of; the

recess 872. It will therefore be seenA that the outer ends of the fingers 83 are freely movable a certain amount radially.

In order to force the sealingv material out of the groove in the outer side of'I the depressed portion ofthe cap and also tohold-` the latter on the body during the seaming operation,l a center pad` 88 is provided which has a peripheral wall 881 the same diameter'l` as the inner diameter of the depression in the cap, and Vmay be slightly tapering so as to gradually press out the interior bead which Corresponde, t0 the exterior-y groovel in.

4882 and is disposed between the top part 833 and the bttomot 4the pad 88, whereby the pad is yieldingly held in extended po` sition, as'sliown in Fig. 9. rl`he center pad 88 carries an annular gas pipe 89 1provided with suitable nozzles 891 which impinge against the wall 881 of the pad so as to heat the pad whereby the sealing or soldering material will flow into place more readily. Gas may be led to the pipe 89 by any suitable means as for example, by a 'flexible tube passing through openings in the top 833 and the member 854.

The seaming operation will now be described. The moment the can reaches the seamingstation S the seeming` mechanism is in the position, as shown in 9,

whereupon the cams, which are continuously I rotatine operate and move the shaping mold and the lingers 82- thereon inwar lly and up`- wardly to the positionv shown in Fig. 10. Simultaneously, the upper corro.gatingor seeming lingers are moved into the position shown in Big. 10, the center pad 88 beine' lower than the two part seeming head, will jreach the head ofthe can lirst and may ield a slight amount to accommodate `cans ol. slightly different heights and the dillerence in the stroke of the seaming' head. the correct arrangemento cans the part 84C has reached and holds the lower limit ol its movement when it and the center pad is in position, as shown in Fig. 1.0, the center pad having pressed the sealing` material from the groove in the cap and flattened out lthe bead.

The annular seaming part 85 rOntinues to move downwardly and thereby carries the outer ends of the lingers 83 down with it, the lingers 82 receding' at the same speed downwardly as the lingers 83 move down` and linally near the end of the downward stroke, receding very rapidly, so as to move the lower corrugatingdevices out ol the way to let the upper lingers 83 finish the corrugating operation. The successive positions of the corrugatinp; and simultaneous bending operation which seams the cap to the can, isshown in detail in Figs. 13 to 19inclusive. rlhe peripheraledge portion Nof the cap and the flange on the can 'being l'lat, as shown in Figs. 13 and'l?, and the upper and lower ,corrugating` and bending); lingers being; on the top and bottom sides oi' the edge of the cap and flange respectively, the lower lingersI are rotated downwardly a distance on their pivots by the cam 79, and the head 84 `presses against the upper end ofthe can while the head 85 having .the hollow part 851.11 moves the outerr ends of the lingers down about their pivots 831 to the position approximately as shown in le and at which point the cams 79 withdraw the mold members 68, 68.1 and lingers 82. As the downward movement of the head 85 continues, the lingers 83 will push the outer ends ot the llange'and ycap downward and then inward located at tbe points where the tongues on l 85 the fcap are positioned and arey somewhat longer than the other lingers, such as the one shown at the right side of the can body in Fig. 10,1 whereby the longer fingers simultaneously corrugate the. tongues and flanges. l

`Near its pivotal connection u831, each. of the upperrow of lingers 83 has a concave recess 836 on its face that engages the surface ol the cap.l The concave recesses in the lingers are arranged in a circular row and are desiggncil `toV simultaneously` form a resilient bead r on the can `body anda simif lar bead Vin the clap which provides an inside groove inthe cap, the bead on the body )fitting intothe groove on theV inside ol' the I lid. It'will be. understood that the resilient bead thus provided onl the cover and formed durinav the corrugating. or searning` operation will more effectively holdV the cover on the can since the cover has a part engagin beneath the shoulder termed by the bead.
